Overview
The Schwarzbeck TSC 7042 is a single-path low-impedance AMN (Artificial Mains Network) designed for conducted emissions testing of automotive components in accordance with Toyota standard TSC7042G. It provides a stable and defined impedance to simulate vehicle power supply conditions, ensuring accurate and repeatable EMC measurements.
The unit supports flexible configuration through external coil connections at terminals K1 and K2, allowing users to adjust inductance to meet specific test requirements. Built for high-current applications, the LISN is well-suited for testing demanding automotive electronics and subsystems.
The EMC Shop customers use the Schwarzbeck TSC 7042 to perform conducted emissions testing under controlled and repeatable conditions. The LISN is placed between the power supply and the device under test (DUT), where it simulates vehicle power line impedance while isolating external noise.
In a typical setup, the DUT is connected to terminal P on the front panel, while the power supply is connected at the rear terminals. The LISN stabilizes the line impedance and enables accurate measurement of conducted emissions using a spectrum analyzer or EMI receiver.
For specific test configurations, engineers may connect an external coil between K1 and K2 to adjust the inductance in accordance with automotive standards. This flexibility allows precise replication of real-world vehicle electrical conditions during EMC validation, troubleshooting, and compliance testing.
